4 Claims.

My invention relates to ventilators and more particularly to astationary type of ventilator for use in buildings or the like.

An object f my invention is to provide a device that may be permanentlyinstalled in the outer wall of a building or enclosure and arranged in amanner to exclude the elements, and lter or screen the air as it entersor leaves the enclosure.

Another object of my invention is to provide a device that may be easilyassembled and installed without the use of special tools.

Another object of my invention is to provide a device that is arrangedto lock into a fixed position when assembled.

A still further object of my invention is to provide a device that iseasily constructed, economical to manufacture, efcient and practical forthe purpose for which it is intended.

It is manifest to anyone familiar with the use of permanently installedventilators that they are quite frequently the cause of snow, rain,insects or the like entering the enclosure. With the device described,illustrated and claimed, these objectionable features are entirelyeliminated. The device is simple in constructtion, may be easilyinstalled and made accessible for cleaning purposes.

Other and further objects of my invention will become more apparent asthe description proceeds and when taken in conjunction with the drawingsin which Figure l is a perspective view of the entire assembled device.

Figure 2 is a perspective view of the angularly disposed housing forminga screening portion for the device.

Figure 3 is a composite perspective rear view of the component partsconstituting the device.

Figure 4 is a vertical cross-sectional view of the assembled device, and

Figure 5 is a horizontal cross-sectional view of the device taken at theline 5-5 in Figure 4.

Similar characters of reference indicate corresponding parts throughoutthe several views, and referring now to the same, the character I0 showsa face plate for engagement with the outer surface of a wall having anaperture through its center and having inwardly disposed members I I, II and I l, thereby forming a frame for the support of a plurality oflouvres or angularly disposed horizontal blades I2. These louvre bladesmay be mounted in a Xed position, or may be pivotally mounted foradjustment. The lower frame section II. is shown angularly dis- 2 i jposed to conform with the angle of the louvre blades I2.

The side frame members I I, are equipped with inwardly extending flangemembers I3 and the lower frame member I I is provided with an inwardlyextending ange member I3. The face plate I0 is shown as having aplurality of apertures I4 therein, in which screws are inserted forattaching the plate I0 to the outer surface of a wall or the like, andwhen the plate I0 is placed in a fixed position, the frame formed by thewalls Il, II and II extend inward for receiving an angularly disposedhousing shown as I5, which has outwardly projecting members IB on thesides and bottom for engagement with the flange members I3 and I3 of theframe, and inwardly extending channel members I1 at the top for theslidable support of a screen or filtering member I8 in the form of aremovable frame equipped with wire screen or the like.

The upper portion II of the frame structure supports a retaining memberI9 arranged to retain the forward end of the filtering frame member I8when the device is in an assembled position as shown in Figures l and 4.

Obviously, the front frame I0 is attached from the outside by means ofscrews through the apertures I4, and the entire frame structureconsisting of a wall I I, I I and Il extends inward, permitting thehousing I5 to be slidably brought into position and held by means of theinwardly extending flange members I3 and the outwardly projectingmembers I 6, after the frame IB has been slidably inserted into thechannel I1, at which time the retaining member I9, which is in aVertical position as shown in Figure 3, is brought down into ahorizontal position as shown in Figure 4, thereby locking the housing I5into position. To remove the housing I5 with the ltering frame I0 inposition, it is only necessary to bend the member I9 upward and raisethe entire housing I5 out of engagement with the frame members.

In the chosen embodiments of my invention, there are many features notheretofore disclosed in the prior art, and although I have shown aspeciiic construction, I am fully cognizant of the fact that manychanges in the form and coniiguration of the engaging channels andflanges as well as the shape and contour of the entire device may bemade, without affecting its operativeness, and I reserve the right tomake such changes as I may deem convenient or necessary withoutdeparting from the spirit of my invention or the scope of the appendedclaims.

member inclined upwardly relative tol the face plate, means for engagingsaid housing at its forward end with said frame, a ltering means, andchannel members formed at the top of the vertical side Walls for theslidable engagement of said ltering means.

2. A device of the character described cornprising in combination a faceplate provided with a central opening therein, said face plate beingvertically disposed, flanges projecting outward from the opening in saidface plate forming a frame, a plurality of louvres angularly disposedwithin said frame, a housing, said housing provided with an open forwardend and having two vertical side walls and a bottom member inclinedupwardly relative to the face plate, means for engaging said housing atits forward open end with said frame, a filtering member and horizontalchannel members formed on the top of vertical side walls of said housingfor slidably engaging said ltering means.

3. A device of the character described comprising a face plate having acentral opening therein, said face plate vertically disposed, flangesforming a frame projecting from the inner edges of the opening in saidface plate and forming a Ipart thereof, a plurality of louvres angularlydisposed Within said frame, a housing, said housing having its bottomupwardly inclined relative to the face plate and open at its forwardend, a pair of vertical side walls, means in the form of anges on saidhousing for slidably engaging said housing at its forward end with saidframe, a filtering means and horizontal channels on the upper edges ofsaid vertical side walls for the slidable engagement of said filteringmeans.

4. A device of the character described comprising a vertical face platehaving a central aperture, flanges projecting outward from said Yfaceplate, said frame consisting of a top portion, a bottom portion and twoside portions, said bottom portion angularly disposed, said side andbottom frame portions provided with anges extending inward, a pluralityof louvres disposed within said framefsaid louvres supported by theinside of said frame and mounted thereto, a housing, said housing havingvertical side walls and being upwardly inclined at the bottom, anges onthe side and bottom walls of said housing for slidable engagement withthe anges on said frame, a ltering means, said housing having the top ofits vertical side walls provided with horizontal channels for slidablysupporting said filtering means.
